Crane brake device convenient to maintain

Abstract

The invention discloses a crane brake device convenient to maintain. The device comprises a crane body; a hoisting suspension arm and a control chamber are mounted over the crane body; wheel bodies are installed at the bottom of the crane body; a brake caliper is mounted in the crane main body; the two ends of the brake caliper are connected with a brake disc through brake friction plates; one endof the brake caliper is fixed with a push rod through a bolt fastener; a positioning pin is installed at the lower end of the brake caliper, a gasket is installed at the upper end of the brake caliper, a fastening block is arranged at the hinged position of the push rod and the brake caliper, a pressure sensor is installed on the brake caliper, a fastening shaft pin is installed on the brake disc, and a hydraulic oil cavity is formed in the brake caliper. According to the crane brake assembly, the interior of the crane brake assembly is improved, the brake disc, the gasket and other assemblies are convenient to disassemble and maintain, meanwhile, the brake disc has the advantages of being good in heat dissipation effect and convenient to install, and the service life of the brake assembly is prolonged.

Description

technical field [0001] The invention relates to the technical field of crane machinery, in particular to a crane braking device which is convenient for maintenance. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Also known as crane, aerial crane, crane. The main features of the tire crane are: the driving cab and the lifting control room are combined into one, and it is evolved from a crawler crane (crawler crane). The shortcomings of crawler cranes (crawler cranes) that crawler shoes cause damage to the road surface are eliminated, and they belong to material handling machinery. Some working characteristics of lifting equipment are intermittent movements, that is, in a working cycle, the corresponding mechanisms for retrieving, moving, unloading and other actions work alternately. The development and use of cranes in the market are becoming more and more e...
